Description

Technical Field

[0001] The utility model relates to a device of a wireless radio frequency identification system, and in particular to an RFID object combination, which comprises an RFID attachment device. Background Art

[0002] Existing RFID (Radio Frequency Identification) functions are widely used by manufacturers, asset managers, and users. By writing to and reading from RFID tags, information can be recorded on the object to which the RFID tag is attached, storing information related to the object within the tag for subsequent use.

[0003] Existing radio frequency identification (RFID) tags are available in both sticker and hanging ring formats, allowing them to be attached to objects by affixing or hanging. While these hangtag-shaped RFID tags can be attached to hand tools, the hanging hangtag can hinder user operation when using such objects. Therefore, improvements are needed to provide RFID devices that allow users to read the RFID tag without protruding too far from the object to hinder operation. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a combination of an RFID attachment device and an object. By designing the RFID attachment device so that it is not easily loosened by external forces after being inserted into the object, the RFID inlay on the RFID attachment device can be firmly attached to the object for the user to read or write information.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an RFID object combination, including an RFID attachment device and an object. The RFID attachment device includes a device body and an RFID inlay; the device body has an axis and includes a head and a body connected along the axis; the head has a receiving groove; the RFID inlay has an insulating carrier, the insulating carrier is embedded in the receiving groove and covers an RFID circuit module. The object has a surface, the surface has an attachment device hole, the attachment device hole has a hole center line and includes an expanded hole portion and a socket portion connected along the hole center line, and the expanded hole portion is adjacent to the surface. The body of the device body is inserted into the socket portion, the head is at least partially inserted into the expanded hole portion, and the ratio of the diameter length of the expanded hole portion to the diameter length of the head is greater than 1.0312 and less than 1.0625.

[0006] The RFID inlay of the present invention is attached to the object by inserting the device body into the attachment hole of the object, allowing an RFID reader to read the information stored in the internal RFID circuit module. The present invention has the advantage that, by designing the diameter of the reamer portion to be slightly larger than the diameter of the head portion, when the device body is attached to the object, the head portion can sink into the surface and its bottom side can be hidden by the reamer portion. This prevents the head portion from being pried up by contact with the inner side of the head portion when an external object collides with the head portion, thereby allowing the RFID inlay to be firmly attached to the object along with the device body.

[0055] In order to more clearly illustrate the present invention, a preferred embodiment is given below and described in detail with reference to the accompanying drawings. Figure 1 and Figure 2 FIG. 1 shows an RFID object assembly 300 according to a preferred embodiment of the present invention. The RFID object assembly 300 includes an RFID attachment device 100 and an object 200 . The object 200 is combined with the RFID attachment device 100 .

[0056] Please see Figures 3 to 7 As shown, the RFID attachment device 100 includes a device body 10 and an RFID inlay 40. In this preferred embodiment, the device body 10 is made of metal and has a certain degree of flexibility. The device body 10 has an axis L1 and includes a head 20 and a body 30 connected along the axis L1. The head 20 has a peak 22 around it. The peak 22 is the most protruding part of the head 20, and the diameter length d2 of the peak 22 is also the diameter length d2 of the head 20.

[0057] The portion of the head 20 adjacent to the body 30 forms an annular surface 24, which is connected to the body 30 and is approximately perpendicular to the axis L1. A necking surface 26 is formed around the side of the head 20 close to the body 30, and the necking surface 26 is connected between the peak 22 and the annular surface 24. The outer diameter of the necking surface 26 gradually decreases from the peak toward the annular surface. The other side of the head 20 away from the body 30 has an arc-shaped top surface 28, and the axis L1 passes through the center of the arc-shaped top surface 28. The periphery of the arc-shaped top surface 28 is connected to the peak 22, and a receiving groove 21 is formed in the middle of the arc-shaped top surface 28. In this preferred embodiment, the receiving groove 21 is a circular groove. In other preferred embodiments, the receiving groove 21 can also be a polygonal groove. The length between the peak 22 and the annular surface 24 along the axis L1 is a peak height h, and the length between the center of the arc-shaped top surface 28 and the annular surface 24 along the axis L1 is greater than the peak height h.

[0058] The body 30 is cylindrical and includes a first section 32 and a second section 34. The first section 32 is connected between the head 20 and the second section 34 along the axis L1. The length of the first section 32 along the axis L1 is greater than the length of the second section 34 along the axis L1. A concave-convex pattern 36 is formed around the first section 32. The concave-convex pattern 36 includes a convex portion 361 and a concave portion 362. The maximum outer diameter D1 of the convex portion 361 of the concave-convex pattern 36 is equal to the maximum diameter D of the body 30. The maximum diameter D of the body 30 is less than the diameter d2 of the head 20. When external pressure is applied to the convex portion 361, the convex portion 361 is forced to deform toward the concave portion 362, elastically reducing the maximum outer diameter D1 of the convex portion 361.

[0059] In this preferred embodiment, the convex portion 361 includes a plurality of ridges 3611 arranged in a circular and evenly spaced pattern around the first section 32, extending parallel to the axis L1. The concave portion 362 includes a plurality of grooves 3621 formed between adjacent ridges 3611, extending parallel to the axis L1. The outer surfaces of the ridges 3611 are connected to form a cylindrical profile, while the inner surfaces of the grooves 3621 are connected to form another cylindrical profile with a smaller diameter.

[0060] The maximum outer diameter length D1 of the plurality of ridges 3611, i.e., the maximum outer diameter length D1 of the convex portion 361 of the embossed pattern 36, is greater than the diameter length d1 of the second segment 34. The minimum inner diameter length d3 of the plurality of grooves 3621, i.e., the minimum inner diameter length d3 of the concave portion 362 of the embossed pattern 36, is less than the diameter length d1 of the second segment 34. In addition to the aforementioned preferred embodiment, in which the convex portion 361 comprises a plurality of ridges 3611 and the concave portion 362 comprises a plurality of grooves 3621, in other preferred embodiments, the convex portion 361 may be a mesh of ridges, and the concave portion 362 may be a plurality of grooves interspersed between the ridges.

[0061] In this preferred embodiment, the maximum outer diameter D1 of the convex portion 361 of the concave-convex pattern 36 is 8.3 mm, and the diameter d1 of the second segment 34 is 8 mm. In other preferred embodiments, the maximum outer diameter D1 of the convex portion 361 of the concave-convex pattern 36 may be greater than 8.1 mm and less than 8.5 mm. To prevent the first segment 32 from being unable to be inserted into a hole due to the maximum outer diameter D1 of the convex portion 361 being too large, or the first segment 32 from being easily loosened after being inserted into the hole due to the maximum outer diameter D1 of the convex portion 361 being too small, the ratio of the maximum outer diameter D1 of the convex portion 361 of the concave-convex pattern 36 to the diameter d1 of the second segment 34 is set to an appropriate value of greater than 1.0125 and less than 1.0625. In this way, when the body 30 of the device body 10 is inserted into the hole, the plurality of ridges 3611 of the convex portion 361 are squeezed and deformed to tightly abut against the inner wall of the hole, so that the device body 10 is firmly combined with the hole.

[0062] The RFID inlay 40 has an insulating carrier 42. In this preferred embodiment, the insulating carrier 42 is an elastic plastic block, and an RFID circuit module 44 is enclosed in the insulating carrier 42. The RFID circuit module 44 includes an RFID chip and an antenna electrically connected to the RFID chip. The RFID circuit module 44 is used to store information that can be wirelessly read by an RFID writing and reading instrument, such as information related to the identity identification of the object 200 attached to the RFID attachment device 100. When the RFID inlay 40 is combined with the device body 10, the insulating carrier 42 is embedded in the receiving groove 21 of the device body 10 and fixed.

[0063] Please see Figures 7 to 11As shown, the object 200 can be an object such as a hand tool, a part of a machine, or a fixture. The object 200 is coupled to the device body 10 of the RFID attachment device 100, allowing the RFID inlay 40 to be attached to the object 200. The object 200 has a surface 50 with an attachment hole 51 formed therein. The attachment hole 51 is configured to receive the device body 10 for insertion and attachment. The attachment hole 51 has a centerline L2 and includes an expanded portion 52 and an insertion portion 54 connected along the centerline L2. The reaming portion 52 is adjacent to the surface 50 and the diameter length D2 of the reaming portion 52 is greater than the diameter length D3 of the socket portion 54. The reaming portion 52 has a hole surface 521 and an annular wall 522 connected to the periphery of the hole surface 521. The hole surface 521 is a circular plane and the hole surface 521 is perpendicular to the hole center line L2. The socket portion 54 is formed in the middle of the hole surface 521.

[0064] To accommodate the body 30 of the device body 10, the length of the insertion hole 54 along the hole centerline L2 is greater than the length of the body 30 along the axis L1. The diameter length D3 of the insertion hole 54 is equal to or slightly greater than the diameter length d1 of the second section 34 of the body 30. For example, in this preferred embodiment, the diameter length D3 of the insertion hole 54 is between the maximum outer diameter length D1 of the convex portion 361 of the concave-convex pattern 36 and the diameter length d1 of the second section 34. The length H between the surface 50 and the hole surface 521 along the hole centerline L2 is greater than the peak height h. The diameter length D2 of the reaming portion 52, that is, the diameter length D2 of the annular wall 522 is greater than the diameter length d2 of the head 20; and the diameter length D2 of the reaming portion 52, that is, the diameter length D2 of the annular wall 522 and the diameter length d2 of the head 20 are preferably greater than 1.0312 and less than 1.0625.

[0065] When the device body 10 is inserted into the attachment hole 51 of the object 200, the length of the insertion hole 54 along the hole centerline L2 is greater than the length of the body 30, and the diameter length D2 of the annular wall 522 is greater than the diameter length d2 of the head 20. In this manner, the body 30 is inserted into the insertion hole 54, and the portion of the head 20 adjacent to the body 30 is placed into the expanded hole 52. During the process of sequentially inserting the second section 34 and the first section 32 of the device body 10 into the insertion hole 54, the multiple ridges 3611 of the protrusion 361 will be compressed by the hole wall of the insertion hole 54 and deformed toward the multiple grooves 3621. Therefore, when the body 30 of the device body 10 is fully inserted into the insertion hole 54, the multiple ridges 3611 can be tightly pressed against the hole wall of the insertion hole 54 and fixed, so that the device body 10 will not be easily detached from the attachment device hole 51 of the object 200.

[0066] The effect of the size ratio between the concave-convex pattern 36 and the second section 34 of the device body 10 is that, by setting the ratio of the maximum outer diameter length D1 of the convex portion 361 of the concave-convex pattern 36 to the diameter length d1 of the second section 34 to be greater than 1.0125 and less than 1.0625, the maximum outer diameter length D1 of the convex portion 361 of the concave-convex pattern 36 will not be too small, resulting in a poor fixation effect when the body 30 is inserted into the attachment device hole 51, nor will the maximum outer diameter length D1 of the convex portion 361 of the concave-convex pattern 36 be too large, causing the multiple ridges 3611 of the convex portion 361 to be difficult to deform and making it difficult for the body 30 to be inserted into the insertion hole 54.

[0067] The size ratio of the head portion 20 of the device body 10 to the reamer portion 52 is such that, when the head portion 20 is inserted into the reamer portion 52, the annular surface 24 abuts against the hole surface 521. The diameter length D2 of the annular wall 522 is only slightly larger than the diameter length d2 of the head portion 20. As a result, the head portion 20 is sunken into the surface 50 and surrounded by the annular wall 522. Any external object colliding with the head portion 20 will only strike the outer side of the head portion 20, such as the curved top surface 28, and will not contact the periphery of the annular surface 24. In this way, external force will only maintain the device body 10 in its inserted position within the attachment hole 51 and will not pry the head portion 20 of the device body 10. Furthermore, the length between the surface 50 and the hole surface 521 along the hole centerline L2 is greater than the peak height h, allowing the necked surface 26 to be buried within the expanded hole portion 52. This prevents external forces from impacting the head portion 20 and prying the head portion 20 upward at the necked surface 26. Therefore, when the device body 10 is inserted into the attachment hole 51 of the object 200, the RFID inlay 40 secured to the device body 10 can be securely attached to the object 200, allowing the RFID circuit module 44 within the RFID inlay 40 to provide information to an RFID-readable and writable device for writing or reading information.

[0068] In addition to the above preferred embodiment, in which the head 20 and the reaming portion 52 are respectively configured as a circular block and a circular groove, in other preferred embodiments, the head may also be a polygonal block, and the reaming portion may also be a polygonal groove. In this preferred embodiment, the preferred ratio of the diameter length of the reaming portion / the annular wall to the diameter length of the head is still a value greater than 1.0312 and less than 1.0625, where the diameter length of the head refers to the diameter length of the circumscribed circle of the head, and the diameter length of the reaming portion / the annular wall refers to the diameter length of the circumscribed circle of the reaming portion / the annular wall.
